I'm looking for information, drawings, pictures, or even the factory video of a Dedalius wing with the movable slat. Any info or comments would be appreciated.  I believe these might have been an option for use on Zenith airplanes.

I would be interested to know what you are up to. I had a lot of Helio drawings that were destroyed by fire and am a big fan of STOL aircraft. I would like to start building a Zenith CH750 soon.   Paul

Hi Mike,

I bought the last Pega-Stol wingkit for the Z-701 from Dedalius' founder, Gilles Boulanger, Phone: 1-819 563-4121 about six years ago..  He sold the mfr'ng rights to someone in Alaska shorly thereafter and I haven't heard anymore about the wingkit since.  Gilles is in his mid-eighties now and wanted to get out of the mfr'ng business and spend more time flying.  The principals who founded the company were an aircraft designer, an aerodynamicist and a professor of engineering. 

The quality of the design and fabrication of the components seem better than the Zenith parts that came with my 701 kit which were certainly very good.  The Dedalius parts are waterjet cut including all rivet holes,insuring distortion-free shapes with no effect on heat treatment, as compared to laser cutting or shearing.  The fuel tanks are roto-molded one piece polyethelene with smoothly radiused edges as opposed to a welded unit made from several pieces with heat affected seams at the areas of highest stress and corners that can trap moisture and corrode.  The slats move on rollers and open /close smoothly with aerodynamic pressure.  The wing is a thinner  NACA  airfoil than the stock Zenith wing and is more than 10% faster at cruise.  The movable slats also allow a 10% slower landing speed with good control.  Gilles says he routinely lands at 25 mph! 

I'm still constructing my 701 after several interruptions for family illnesses, a cross-country move and now joint problems of my own that preclude standing for long periods.  As a 70 year old retired aerospace engr.(Hughes Aircraft), I probably would have bought a finished plane had I known what the future held, but hindsight ...

I might consider selling the entire kit including the wings, in case you're interested.  I have all the doumentation, aero analyses, and DVDs of the construction process including the aircraft flying.

Hope this helps,

Neil H. Naves

Hello,

    Don't mean to high jack this thread but I have also been looking for this information about the Dedalius wing .I had spoke with Gilles many years ago about his wing . At the time it seemed too be to good to be true. Didn't seem to be a top discussion among the 701 group either so I put the idea aside. I couldn't remember the name of the wing but remembered they were in QB Canada ?? 

     Neil I might be interested in your complete kit if Mike is not. 

                                                                                                                               Thank You for the information, Dana Young

                                                                                                                                GT Falls, MT

Hello Paul,

 

I'm just very interested in planes with slats/slots and would like to adapt some to another plane if I can get the right info.

Hi Mike, I sent an e-mail.  I would also recommend the book on Helio's by Frank J. Rowe. There is a lot of information on stol aircraft in the first few chapters of all types.    Paul
